    Abstract: A degradation-free, low-permittivity dielectrics patterning process for damascene starts with provision of a substrate, wherein the substrate has a dielectric layer and a via plug formed on it. Then, a inter-metal dielectric layer and an insulating layer are formed in sequence on the dielectric layer. A hard mask layer is next formed on the insulating layer, and is subsequently patterned. An etching process is performed on the insulating layer and the inter metal dielectric layer by using the patterned hard mask layer as a mask to form a metal line trench and expose the via plug. The metal line trench is then filled with metal by forming a metal layer on the hard mask layer. A metal line in the shallow trench is formed by performing chemical mechanical polishing on the metal layer to expose the insulating layer, and then performing post-chemical mechanical polishing cleaning.

    Abstract: A method of fabricating an unlanded metal via of multi-level interconnection. The method is characterized by utilizing damascene scheme to form a metal wiring layer so that the processes are simplified. Moreover, by this method of the invention, a problem of difficulty in filling dielectric material between the metal wiring lines can be avoided and the metal layer does not have to be etched prior to filling the dielectric material. Further more, an etching stop layer is formed over the first inter-metal dielectric layer to avoid overetching during the formation of metal via, which therefore avoid short circuit. Forming the metal wiring lines by damascene scheme allows the etching stop layer to be easily formed over the first dielectric layer, without over etching the metal via.

    Abstract: The present disclosure provides a poly resistor on a semiconductor device and a method of fabricating the same. In an embodiment, a poly silicon resistor device is formed by providing a substrate having a first region and a second region. A dummy gate stack is formed on the substrate in the first region, wherein the dummy gate stack has a dummy gate stack thickness extending above the substrate. A poly silicon resister is formed on the substrate in the second region, wherein the poly silicon resistor has a poly silicon resistor thickness extending above the substrate a distance which is less than the dummy gate stack thickness. A dopant is implanted into the substrate in the first region thereby forming a source region and a drain region in the first region of the substrate. The dopant is also implanted into the poly silicon resistor. An inter-level dielectric (ILD) layer is formed on the substrate over the dummy gate stack and also over the poly silicon resistor. The ILD layer is planarized, thereby exposing the dummy gate stack and leaving a portion of the ILD layer over the poly silicon resistor. The dummy gate stack is replaced with a high k metal gate while using the portion of the ILD layer over the poly silicon resistor as a mask to protect the poly silicon resistor during replacement of the dummy gate stack with the high k metal gate.
